The valve is only suitable for use in the whole paper and seated, to adjust and throttling is not allowed. Pneumatic by the loss of air pressure in the common need try our best to take care of function, generally choose single cylinder utility. Simple structure, production and maintenance more convenient. Think flow from the special nature of the problem, as of valve and ball valve with short journeys, opening and closing speed, tightly closed good, opening and closing of static torque and small unique place, two kinds of products have applied. Small office tour, opening and closing time is short. Pneumatic globle valve general all closed for the whole paper. Obviously with different inlet position, push rod has a different direction. Uncomfortable or used for larger particles, viscosity, easy to medium of coke. The lack of the valve as follows: the fluid resistance is big, open and close the required force is larger. By contrast inlet position when putting on the same side, intake makes putting back, this form according to the utility of cylinder. When the inlet position in putting back cavity, intake that putting forward, this form is called cylinder is utility. But from a reliable sex thinking problem, main is small products or pneumatic by valve. Single cylinder with reset spring, utility products have loss of air pressure semi automatic reset function, that is, loss of air pressure cylinder piston ( Or diaphragm) Under the spring utility, angry push rod cylinder return cylinder displacement at first position ( The original position of trip) 。 Tightly closed, tightly closed between friction force is small, the survival of the fixed number of year is longer than the other. Q: pneumatic by the valve's unique place is what? A: pneumatic opening and closing of the valve is the plug valve, tightly closed like the simplest surface or cone, the disc along the fluid core line of linear motion. Poor regulation performance. Air from inferior vena into the piston push rod progresses Marine valve movement. Double with cylinder without the reset spring, putting in a cylinder gas source must depend on transformation of the entrance location. Stem has up and down movement way, the lever ( The valve stem up and down, the handwheel is not up and down) , there are up and down rotating lever ( The handwheel with spin up and down together, the stem nut is located in the body) 。 Gas source from the piston chamber into the push rod downward movement. Pneumatic cylinder of the valve to finalize the design product, according to the utility form can be divided into single and double effect using two kinds of utility. Because without a reset spring, double effect compared with the cylinder with the diameter of single cylinder utility has bigger thrust, but I don't have semi automatic reset function. 。 Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you.
